Single-Electron Transfer from Dimsyl Anion in the Alkylation of Phenols
摘要:
While attempting to synthesize biaryl ethers we discovered the inadvertent formation of a methylsulfoxylmethyl ether byproduct. Formation of this unexpected byproduct presented an opportunity to streamline the synthesis of methylsulfoxylmethyl ethers. Mechanistic studies suggest a radical pathway with dimsyl potassium as a reducing agent.

A dispersion of a water-insoluble colorant containing: a medium containing water; fine particles of the water-insoluble colorant; and a polymer compound or a surfactant that includes at least one kind of electron-withdrawing group or group of atoms represented by any one of formulae (I) to (IV) as its hydrophilic part:
wherein at least one of X

is not the linking group, the at least one of X
1
and X
2
represents an electron-withdrawing substituent; R
